Logically, I doubt there's any register linkage between the two distinct
functions you're talking about - have you checked to see if your board
design has a mistake on it? Perhaps some coupling? Board defects?
Schematic errors?

Now I have two qustions about DM6446 EVM.
the First is:I want to know how the OS can detect the MMC/SD when the system

We know that the MMC/SD Card Detect pin is connected to the MSP430
P2.1/INCLK pin. So I want to know the reasons about it.
Because on our board we

You will definitely need to change the NAND_MAX_OOBSIZE to 128 for 4K pages.
You may also need to change the FFCHARS definition to 4096 to be safe.
